Question

1. Sum of two numbers is 25 and the difference is 13. What are the numbers ? (a) 12, 13 (b) 21,4 (c) 14, 11 (d) 16,6​

Answer 1

Answer:

a) 12 is the answer for your question

Answer 2

Answer:

x = 19

y = 6

Step-by-step explanation:

Let the numbers be 'x' and 'y'

Sum of to numbers is 25

$\bold{\red{ x + y = 25 --------- (1)}}$

And the difference between these two numbers is 13

$\bold{\red{ x - y = 13 --------- (2)}}$

Solve equation (1) & (2)

We get,

2y = 12

⇒ y = 6

Substitute the value of 'y' in equation (1) or (2)

x - y = 13

x - 6 = 13

x = 13 = 6 = 19
